Referring more particularly to Figures 1 to 7, inclusive, it will be noted that there are disclosures of a modified construction of the thread guide and slub catcher. As in the thread guide and slub catcher illustrated in Figures 1 to 3, the modified construction includes a shank which enters a socket in a support 7* in the spinning frame, being removably secured to the socket by means of a set-screw 8 The other end of the shank terminates in a disk or segment 17 in the periphery of which a circular recess 18 is formed. One edge of this recess is beveled oii or countersunk and has a polished surface in order to readily guide the thread therethrough. This recess is formed at a location substantially opposite the shank where it connects with the disk or head. Projecting from the disk in close position to the recess 18 is a lug 19 which acts as a guard for the thread, also as a guide for directing the thread toward and into the recess 18. The edge of the lug or guard is substantially in alinement with one edge ot the shank and projecting from one edge of the disk adjacent the lug is an arcuate tongue 20 which terminates in a horn 21. The horn is straight in a direction at right angles to the disk and projects from the arcuate tongue in a plane parallel with the face of the 'disk.

Secured on one face of the disk which is carried by the shank is an additional disk 22. A screw passes through the disk 22 and is threaded into the disk 17. This screw 23 may be loosened or tightened whereby the disk 22 may be adjusted. The disk 22 has adjacent its edge a plurality of slots 24:. These slots are constructed of various widths, depending entirely on the size of the yarn which passes through them. In the operation, the disk 22 is adjusted so that one edge of either one of the slots 24 may be disposed in a plane with the plane of one edge of the lug which is adjacent the circular recess. The horn 21 is disposed so that its edge portion 25 will lie across one of the slots of the disk 22, it depending en tirely upon the adjustment of the disk. In

fact, the edge 25 of the horn assumes a posicenter of the disk 22.

tion substantially half way between the open end and the crotch of the slot and the horn beyond this point merges into an arcuate portion 26 which is concentric with the At a point a little beyond the arcuate portion 26, the horn terminates in an extension 27 which is curved in a direction opposite to the curvature of the arcuate portion 26. This curved extremity 27 acts to guide the thread between the curved portion of the horn and the disk 22 whereby the thread may enter the slot which may be disposed adjacent the edge 25 of said lug. When the thread is guided to this position, it will engage the slot and should there be any slubs or enlargements in the thread, during its passage from the bobbin to the spinning mechanism and thence to the spools, the thread may or may not break, it depending entirely upon the tension on the thread during its passage from the bobbins. The edge 25 of the lug acts to direct the thread into the slot which may be disposed adjacent the edge 25. However, should the thread break, it may be subsequently pieced or spliced, the splice being of such size as to pass through the slot readily during its passage from the bobbins to the spinning mechanism and thence to the spools of the spinning machine. By loosening the screw which fastens the disk 22 to the disk 17, the disk 22 may be adjusted so as to be disposed in one of the slots in the proper position to receive the thread. Should the thread to operate through the spinning machine be increased in diameter, a larger slot may be. disposed to permit of the passage of the thread and should a smaller thread be used 'on the spinning machine, the disk may be adjusted to arrange a smaller slot in position for the reception of the thread.

The invention having been described, what is claimed is:

1. The combination with a spinning machine of a thread guide andslub catcher interposed between the bobbins and the spinning mechanism, said guide having a slot and a guide lug adjacent thereto, and a horn or projection overlying the slot and spaced from the face of the guide for directing a thread toward and into engagement with the slot.

2. The combination with a spinning machine, of a thread guide and slub catcher comprising a disk provided with a guide lug, a member a'djustably secured on the disk and provided with a ,slot adjacent to the guide lug, and a projection overlying the slot for guiding a thread toward and into engagement with the slot.

3. The combination with a spinning machine, of a thread guide. and slub catcher interposed between the bobbin and the spinning mechanism, said thread guide and slub catcher comprising a member, an element secured 011 the member and having a guide space, and a horn overlying the guide space and spaced relatively close to the element for directing the thread toward and intothe space.
